'Mad Men' premiere ratings tumble, 'Game of Thrones' stays hot

The season premiere of
"Mad Men" took a ratings hit, falling to its lowest debut numbers since 2008.

AMC says 2.3 million people watched the show Sunday (April 13), the smallest premiere audience since the Season 2 debut in in July 2008. It was down about 32 percent from the 3.37 million who tuned into the Season 6 premiere last year.

On the bright side for AMC, episode 2 of
"Turn" held onto most of its premiere audience. The Revolutionary War drama scored 1.9 million viewers Sunday, down only slightly from the 2.1 million who saw the series premiere the previous week.

Elsewhere Sunday, HBO's
"Game of Thrones" followed its
record-setting season premiere with more strong ratings. Sunday's show drew 6.3 million people, the series' second most-watched episode ever behind only the 6.6 million who saw the Season 4 premiere.

"Silicon Valley" (1.7 million, down from 2 million) and
"Veep" (860,000, down from 1 million) also held up fairly well for HBO.
